AccuRender nXt

advanced rendering for AutoCAD

I've just implemented Intel's denoising library in AccuRender Studio. I think the results are very exciting.  Most models seem to be something like 4-10 times faster(!).  I'm pretty darn sure this makes AccuRender Studio faster than the original Standard Engine, with much better results and much less monkeying around (no daylight sources, reflective shaders, etc.)

The Intel Open Image Denoise, unlike nVidia Optix (which I had previously implemented), does not require a specific GPU.  It runs on modern Intel CPUs and seems to be equally fast and perhaps a little better in quality.

You can get it on the Download->AccuRender Studio page.  Please note that I have changed the names of the AutoCAD plugins, so early adopters will have to repeat the netload command step.

I do have a relatively fast 16 core machine, however, this one ran for one minute(!):

This one ran for five minutes-- it's got a ways to go but this level of completion would have been hours and hours before.

More to come.

this looks excellent, I've just upgraded to AutoCAD2020, would you be working on an arstudio plugin for 2020 soon? 

I'll check and see if the development tools are out there yet.  If so, I can build one right away and you can test it for me.

It looks like the 2019 version should work.  Give it a try and let me know.  I will change the online instructions to reflect this.  (The 2019 version nXtRender should work as well, I think).

Yes, I have loaded the 2019 version and all seems to be working fine!

Right.

AutoCAD 2020 is Release 23, just like AutoCAD 2019, so you just need to APPLOAD the 23 module for AutoCAD 2020.

It would be useful if you could adjust the amount of denoising as it tends to hide details and textures.

On a different point. When the preview render is paused, as soon as you alter the view, the rendering commences, but the symbol in the top left corner still says it is paused.

It isn't adjustable-- you can turn it off if you want in the Adjust Image tab.  It isn't perfect, it will blur some detail particularly early on, but does tend to resolve really nicely and much faster than the noise would.

I'll check out the pause issue.

When I click on the Open Material button I get the following error:

Then when I click on OK, I get this:

Is anyone else seeing this when clicking on the Open Materials button?

No, it works for me.

Is there a way of straightening the verticals, or does that now have to be done in Photoshop?

There is a 2 point perspective under camera-- if that's what you mean.
